SSL Validation Levels
DV - Domain Validation - Provide the lowest level of validation available from commercial certificate authorities. Unlike high-assurance or EV SSL certificates, DV certificates do not require a human element in the certificate issuance process or additional organizational validation processes.
OV - Organization Validation - Involves full business and company validation from a certificate authority using currently established and accepted manual vetting processes. You will be required to prove that you are a legitimate company. Each certificate comes with a warranty, Corner of Trust (Comodo) or Dynamic Site Seal (GeoTrust) trustmark, and is 2048 bit ready.
EV - Extended Validation - Provide the highest levels of encryption, security, and trust to your customers and improve conversion rates. EV certs reassure visitors that it is safe to conduct online transactions by turning the address bar green on popular browsers.
